Neutron Electric Form Factor from 3He(pol)(e(pol),e'n)

Abstract

In a double polarised electron scattering experiment data have been taken from which $G_E^n$ can be extracted for $Q^2=0.2{GeV}^2/c^2$. We have measured asymmetries corresponding to the spin-spin correlation functions $A_x^{\prime }$ and $A_z^{\prime }$ and to the target analyzing power $A_y^0$. In order to investigate the influence of the reaction mechanisms and the different components of the ${}^{3}He$ wave function, also the $(e,e^{\prime }p)$ and $(e,e^{\prime }d)$ channels have been measured simultaneously. Some preliminary results are presented.
